Unfortunately it's white glare, so that rules out any cleverness using Channel Mixer or Levels or anything else.
So it's going to have to be hard cloning work.
You'll begin by repairing the camera-right eye, because it's the least damaged. Most of it will be cloning, but you'll also copy and flip the little bit of clear tear duct area from the other eye.
Take your time with this, it's difficult work.
Then, when that eye is completely repaired, you can copy (but not flip) it across to the camera-left side to repair the damage there.
